What it does
XLSX Processing Openai is an agent skill from lawve-ai/awesome-legal-skills. Toolkit for comprehensive Spreadsheet reading, creation, editing, and analysis with visual quality control. Use to work with spreadsheets (.xlsx, .xlsm, .csv, .tsv) for: (1) Creating new spreadsheets with formulas and formatting, (2) Reading or analyzing tabular data, (3) Modifying existing spreadsheets while preserving formulas, (4) Building financial models with proper formatting, (5) Data visualization with in-sheet charts, or any other spreadsheet tasks.
Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 9 other files, including reference files (for example `README.md`, `references/examples/openpyxl/create_basic_spreadsheet.py` and `references/examples/openpyxl/create_spreadsheet_with_styling.py`).
It sits in Documents & Office, covering Excel spreadsheets. It works with Microsoft Excel, OpenAI, openpyxl and LibreOffice. The repository describes itself as: A curated list of awesome Agent Skills for automating legal work. The licence is Apache-2.0.
When your agent uses it
- Work with spreadsheets (.xlsx
- Creating new spreadsheets with formulas and formatting
- Analyzing tabular data
- Modifying existing spreadsheets while preserving formulas
Example prompts
- “/xlsx-processing-openai”
Requirements
- Python 3
Workflow steps
5 steps, taken from the first numbered list in SKILL.md.
- Confirm the file type and goals (create, edit, analyze, visualize).
- Use openpyxl for .xlsx edits and pandas for analysis and CSV/TSV workflows.
- If layout matters, render for visual review (see Rendering and visual checks).
- Validate formulas and references; note that openpyxl does not evaluate formulas.
- Save outputs and clean up intermediate files.
What it can do on your machine
Read from SKILL.md and the folder at commit 045f738. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Ships script files (Python), which the agent can run.
Shell commands in SKILL.md call:
uvpython3brewapt-getsofficepdftoppm
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use uv, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
XLSX Processing Openai loads about 1.3k tokens when it runs, and up to ~3.4k if it reads all its reference files. Until then it costs about 121 tokens; SKILL.md has 594 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check: notes
The automated check noted patterns worth knowing about, such as sudo or a known installer.
- NoteRuns commands with sudoSKILL.md:68
sudo apt-get install -y libreoffice poppler-utils
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Spreadsheet Skill (Create, Edit, Analyze, Visualize)
When to use
- Build new workbooks with formulas, formatting, and structured layouts.
- Read or analyze tabular data (filter, aggregate, pivot, compute metrics).
- Modify existing workbooks without breaking formulas or references.
- Visualize data with charts/tables and sensible formatting.
IMPORTANT: System and user instructions always take precedence.
Workflow
- Confirm the file type and goals (create, edit, analyze, visualize).
- Use
openpyxlfor.xlsxedits andpandasfor analysis and CSV/TSV workflows. - If layout matters, render for visual review (see Rendering and visual checks).
- Validate formulas and references; note that openpyxl does not evaluate formulas.
- Save outputs and clean up intermediate files.
Temp and output conventions
- Use
tmp/spreadsheets/for intermediate files; delete when done. - Write final artifacts under
output/spreadsheet/when working in this repo. - Keep filenames stable and descriptive.
Primary tooling
- Use
openpyxlfor creating/editing.xlsxfiles and preserving formatting. - Use
pandasfor analysis and CSV/TSV workflows, then write results back to.xlsxor.csv. - If you need charts, prefer
openpyxl.chartfor native Excel charts.
Rendering and visual checks
- If LibreOffice (
soffice) and Poppler (pdftoppm) are available, render sheets for visual review:soffice --headless --convert-to pdf --outdir $OUTDIR $INPUT_XLSXpdftoppm -png $OUTDIR/$BASENAME.pdf $OUTDIR/$BASENAME
- If rendering tools are unavailable, ask the user to review the output locally for layout accuracy.
Dependencies (install if missing)
Prefer uv for dependency management.
Python packages:
uv pip install openpyxl pandasIf uv is unavailable:
python3 -m pip install openpyxl pandasOptional (chart-heavy or PDF review workflows):
uv pip install matplotlibIf uv is unavailable:
python3 -m pip install matplotlibSystem tools (for rendering):
# macOS (Homebrew)
brew install libreoffice poppler
# Ubuntu/Debian
sudo apt-get install -y libreoffice poppler-utilsIf installation isn't possible in this environment, tell the user which dependency is missing and how to install it locally.
Environment
No required environment variables.
Examples
- Runnable Codex examples (openpyxl):
references/examples/openpyxl/
Formula requirements
- Use formulas for derived values rather than hardcoding results.
- Keep formulas simple and legible; use helper cells for complex logic.
- Avoid volatile functions like INDIRECT and OFFSET unless required.
- Prefer cell references over magic numbers (e.g.,
=H6*(1+$B$3)not=H6*1.04). - Guard against errors (#REF!, #DIV/0!, #VALUE!, #N/A, #NAME?) with validation and checks.
- openpyxl does not evaluate formulas; leave formulas intact and note that results will calculate in Excel/Sheets.

Citation requirements
- Cite sources inside the spreadsheet using plain text URLs.
- For financial models, cite sources of inputs in cell comments.
- For tabular data sourced from the web, include a Source column with URLs.
Formatting requirements (existing formatted spreadsheets)
- Render and inspect a provided spreadsheet before modifying it when possible.
- Preserve existing formatting and style exactly.
- Match styles for any newly filled cells that were previously blank.
Formatting requirements (new or unstyled spreadsheets)
- Use appropriate number and date formats (dates as dates, currency with symbols, percentages with sensible precision).
- Use a clean visual layout: headers distinct from data, consistent spacing, and readable column widths.
- Avoid borders around every cell; use whitespace and selective borders to structure sections.
- Ensure text does not spill into adjacent cells.
Color conventions (if no style guidance)
- Blue: user input
- Black: formulas/derived values
- Green: linked/imported values
- Gray: static constants
- Orange: review/caution
- Light red: error/flag
- Purple: control/logic
- Teal: visualization anchors (key KPIs or chart drivers)
Finance-specific requirements
- Format zeros as "-".
- Negative numbers should be red and in parentheses.
- Always specify units in headers (e.g., "Revenue ($mm)").
- Cite sources for all raw inputs in cell comments.
Investment banking layouts
If the spreadsheet is an IB-style model (LBO, DCF, 3-statement, valuation):
- Totals should sum the range directly above.
- Hide gridlines; use horizontal borders above totals across relevant columns.
- Section headers should be merged cells with dark fill and white text.
- Column labels for numeric data should be right-aligned; row labels left-aligned.
- Indent submetrics under their parent line items.
